Thank you for your question. The medical evidence that is exists at present regarding the use of this melatonin, niacin for growth is inclusive. However, exercise and adequate sleep has been proven to be a vital component of healthy growth, and the prevention of disease. We recommend that you continue to exercise and have adequate sleep each day. We do not recommend taking melatonin and niacin supplements for the purpose of growing taller. In fact, growth is almost entirely determined by genetic inheritance from one's parents. Please be guided accordingly.
